What problem does it solve? Multi-model debates collapse into early herding when panelists see each other's views too soon, and ungrounded models win arguments by importing private facts. This Skill produces one panelist's independent opening position, grounded strictly in a shared evidence pack, so the debate starts from genuinely divergent, verifiable stances. ## Core Features & Use Cases - Independent Opening Positions: Each panelist (P-codex, P-gemini, P-claude) answers the proposition and every contested question without seeing any peer's output, preventing anchoring. - Closed-World Citation: All claims cite only [g-n] items from the grounding pack, with an uncited_assertions honesty ledger for anything ungrounded. - Structured Output Contract: Emits exactly one JSON position object per CLI call with identity stamping, stance, answers, key claims, and the strongest counterargument to its own view. - Use Case: A driver running workflows/brainstorm.yaml fans this Skill out across three CLI panelists in parallel, collecting three divergent position objects as round 0 of a structured debate on a technical proposition. ## Quick Start Run the panel-open stage of the brainstorm workflow to have each panelist produce an independent opening position from the debate brief and grounding pack.
